Police: Parents of missing baby not cooperating

View full size(AP Photo/Family Photo via The Kansas City Star)An undated family photo of Lisa Irwin, now 10-months-old, is shown at a news conference in Kansas City, Mo., Wednesday, Oct. 5, 2011. The parents of Lisa made a tearful plea for the child's safe return Wednesday, nearly two days after she disappeared, begging her abductor to drop her off someplace safe.

Kansas City police spokesman Steve Young said Thursday night that Deborah Bradley and Jeremy Irwin have decided to stop talking to detectives. He didn't provide details.

But he did say the couple's claim that their cellphones were stolen hasn't produced any leads that investigators could pursue.

Young says police still have no suspects in the disappearance of their daughter, Lisa Irwin. Her parents say she was snatched from her crib sometime late Monday or early Tuesday.

During a tearful news conference earlier Thursday, her parents described how they frantically searched their home for any sign of their daughter but found only an open window, an unlocked front door and house lights blazing.
